potential heat value
解釋
潛熱值-
Temporally, annual potential evapotranspiration is from 882 to 107 lmm, with a mean value of 974mm at qiabuqia ; and it is positively correlational to precipitation and temperature, so it is beneficial for plant growth because precipitation and heat ocurs at the same growth period. ; spatially, annual potential evapotranspiration is from 485mm to 1174mm, with a mean value of 1027mm, and it ' s spatial distribution is negatively correlational to precipitation and slope, whereas positively correlational to temperature and extra solar radiation, therefore the spatio - temporal difference of water become the key factors to plant growth and plant climate potential productivity
在青海共和盆地,歷年潛在蒸散平均974mm ,各月潛在蒸散與降雨和溫度之間是很好的正相關,所以雨熱同季有利於作物生長:年潛在蒸散的空間分佈范圍從485 ? 1174mm ,平均1027mm ,而且年潛在蒸散空間分佈與降雨和坡度是負相關,與溫度和大氣外層輻射正相關,因此水分和溫度的是影響作物水分耗散的重要因子,決定了共和盆地植被的氣候生產力。
